DEVICE IN MOTOR-PLOWS.

Application filed November To all whom t may concern.'

Be it known that we, RUDOLPH GUs'rAv ANDERSEN, engineer, and ALBERT BERNHARD CHRISTIAN HANSEN, engineer, subjects of the Kingof Denmark, residing at Copenhagen, in the Kingdom of Denmark, have invented new and useful Improvements in Devices in Motor-Flows, of which the following is a specification.

The present invention refers to a device in motor plows. The characteristic feature Y of the invention is that each plow is connected by means of a joint to an arm revoluble around a shaft. They joints are forkshaped and of such a width that they, in combination with the arms, serve as guides for the plows, and prevent them from turning. On the naves of the arms there are tappets corresponding to tappets on the sockets which are keyed onto the shafts. The stationary tappets on the shafts are, while the motor plow is working, adjusted to such a position that they do not obstruct the free, upward movement rof the plow from the greatest desired plowing-depth. The shafts can be turned simultaneously, so that the plows can" be lifted simultaneously by the stationary tappets on the shafts engaging the tappets disposed on .the arms, when the tappets are turned together with the shafts. The joints are secured to the plow beams in front of the vertical plane through the point of gravity of the plow, so that the front end of the plow beam is first lifted up from the ground, whereby .the plow-shares are Vcaused to assume an oblique position, with the points turned obliquely upward, so that they slide up out of the ground as on an inclined plane.

The invention is sety forth in the accompanying drawing, in whichn Figure 1 is a vertical, longitudinal section of a part of a motor plow, with the plow shares in the lifted position, Fig. il is a top view of the same, Fig. 3 is a view in perspective showing on a larger scale certain details of construction. 1 is the frame ofthe motor plow, to which frame the plows are secured in an ordinary, previously known manner by means of traction bars 2. 3 are shafts, which are jourualed transversely in the frame 1. On the shafts 3 there are fast disposed sockets 4: (Figs. 2 and 3)', on both sides of a'revoluble nave 5, which carries an arm 6, the free end Specification of Letters Patent.

11 is a two-armed ,lever fast disposed on:

one of the shafts 3 the upper end of which lever isconnected with a cog-rack V12, which is shiftable lengthwise in the longitudinal direction of the motor plow, and which is disposed above. the frame 1. 18 is a cogwheel, or the like, which meshesy in between the cogs of the cog-rack 12, and which is loosely disposed on a driving shaft14, but can be fastly connected with it. 15 isa traction bar, whichconnects the cog-rack 19 with any arm 16 extending from the rear shaft 3, andk 17 is a tractionbar which .connects the lower end of the lever 11 with an arm 18 extending from the front shaft 3.

Vhen the plow shares are to be lifted during plowing, the cog wheell is fastly connected with the shaftll, and it then turns Atogether withthe shaft, wherebyn the cograck 12 is pulled forward until the cog wheel runs free of therlast cog on the cog-rack12. On the shifting of the latter, all the shafts are simultaneously turned by means of the lever 11, the traction bars 15 and 17, and the arms 16 and 18, whereby the tappets 10 on the sockets 4 are caused to mesh with the tappets 9 on the naves 5, so that the arms 6 oscillate around the shafts 3, and the links (and-thereby also the plows) are lifted. When Vthe links are'connected with the plow beams 8 in front of thevertical plane through the point of gravity of the plow, the front end of the plow beamv is rst lifted up from the ground, and the plow share is thereby caused to assume an oblique position, with the point turned obliquely upward, so that it can slide up out of the ground as if on an inclined plane.

The plow shares are held in the lifted position by means .of a hook 19, which meshes in over a ratchet-like arm 2O on one of the shafts 3.

When the plow share is to be lowered again, the hook 19 is lifted up from the ratchet 20, after which the plows are lowered to the ground by means of their own weight. When the tappets 9 on the naves 5 mesh iookv iio vits vwill 'Shaft Y Y v fsaidflevers, and 4Corresponding tappets carwith the tappets 10 on the sockets l fast disposed on the shafts, the shafts are turned atthe ,Sametime that ,the plow sharesare lowered, and the cog-raok l2 yis thereby moved back by means of the lever 11. While the motor plow is working, the tappets 10 remain standing in the same position, and Athe ploiws can be moved, independent -of one another, in a Vertieal direction, since the arms 6 can be turned around the shafts.

Havingnow partieularly described and of our said invention same is to beperformed,we`deelare that Ywhat we claim is:- 15

several shares, levers suspending the 'shares whereby theshares are adapted to be vlifted simultaneously, shafts for said levers whereby .each lever is revolubly mounted on .its`own.s haft, tappets carried each vof levers, and corresponding tappets carried by Aea'oh'of the shafts, said tappets beling iadapted to coperate when all the plow l'shares'iare to vbe* lifted simultaneously, but eavingl each individual plowl share free to move upward independently of the other ones, plowbeams'for the shares, vand forkshaped linkspivotally connected toy said' vlevers and beams and adapted to resist the lateral thrust( tendingto'foree the shares sidewise.
